Many Android smartphone fans will agree that custom OEM user interfaces for Android often muddle the user experience. Some users prefer the standard Android interface, but much of the ire felt against custom user interfaces on Android is that they often significantly delay the rollout of operating system updates.

One Android user interface that has drawn its share of criticism is HTC's Sense UI.

HTC's chief product officer, Kouji Kodera, has gone on the record saying that Sense UI has become too complicated. According to Kodera, despite the fact that millions of HTC users like Sense UI, it has become too cluttered and complex.

"From the original Sense up to Sense 3.5 we added too many things. The original concept was that it had to be simple and it had to be easy to use and we had that philosophy, but over time it got cluttered."

"There were too many things in there," Kodera continues. "Even on the home screen we had four or five icons before consumers got a chance to add things themselves. For the HTC One range we have taken it down to Sense 2 again."

Kodera promises that the fourth version of HTC's interface is much more refined. He also promises that the new version doesn't completely shed the Android operating system just for the sake of covering it up.

"What we've done right now is a good mixture of keeping Sense and Google's Ice Cream Sandwich element in a good balance. We haven't tried to change everything here. We have kept a lot of the ICS element but still added the Sense flavour on top of it."
